The purpose of this study is to create a lesson plan using teaching materials which help students to get interested and to work autonomously. As the appropriate material for the purpose, the researcher chose students' own school life as a topic. Students chose one situation and write a description in English for an assistant language teacher (=ALT), using a picture of the situation. According to the reflection cards of students, 90% of them thought the activity in groups positively. They presented the description to ALT, showing the picture. Two students changed their thought of speaking and liked speaking activities. Therefore, using familiar material lead students to get interested, and thus, choosing school life as a topic worked effectively.
